To setup your computer to send/receive email, you must already have the email account created in your Control Panel. You will need the following information when following the step by step instructions below for your email program.
Username: email@example.com (your full email address)
Password: use whatever password you were assigned
Incoming Mail Server: mail.yourdomain.com (replace yourdomain.com with your domain name)
Outgoing Mail Server: mail.yourdomain.com (replace yourdomain.com with your domain name)
Authentication: The outgoing mail server will require password authentication to send mail. The incoming does not. You do not need SSL or anything else it might ask you.
If you have any trouble setting up your accounts or sending email, refer to the email troubleshooting section of this website.
